The state’s Department of Law found no legal problems with the rules approved by marijuana regulators in December that will govern where and how on-site consumption takes place.

The rules were recently sent to Lt. Gov. Kevin Meyer, whose signature is required for the rules to be filed.

Regulations could become effective 30 days after filing.

Interested businesses will have to apply for a special on-site use endorsement and devise plans that meet security, ventilation and other standards and pass muster with the state’s Marijuana Control Board.

Some in the industry predict it’s possible the first on-site use areas could be approved by this summer.
